puzzles and two “greater than” sudoku puzzles and one “greater than-killer” sudoku puzzle. You can play
any of them online or print them out to play
offline. Older puzzles are in the archives. Older puzzles are also listed by difficulty. Generally, the weekly puzzles are harder than the daily puzzle. Have Fun!

Puzzles get harder as the week progresses, with Sunday's
puzzle generally being the hardest. However, for those of you who want
something harder to work on during the week, we also have a harder
killer board here. A new one will be presented each week. Solutions
for the daily puzzle are posted the following day in the archives. Solutions to the weekly puzzle are
posted a week later, also in the archives.

If you are looking for something a bit
different, why not try out our “Greater Than” or our “Greater Than” Killer sudoku
puzzles. Regular sudoku rules apply with the additional requirement
that if a >, <, or = sign appear between two cells (or cages) then the values
in the cells (or cages) must obey the relation. Let us know if you
like these puzzles and how hard you find them.

The “Greater Than” Killer sudoku take killer sudoku to a new extreme. Some of the cages have no sum value attached. You must determine what the individual cells in the cage sum to by looking at surrounding regions. If there are relations between the cages (e.g., >, <, or =), the cages will obey those relations. Beware, these puzzles can be very hard!
